3 checks · 2 src · 4/13/2026
⚠ Checks disagree: 1 unverifiable, 2 confirmed

The source confirms Ben Mann as a co-founder of Anthropic and that Anthropic was founded in 2021. The startDate of 2021-01 (January 2021) is consistent with the founding year stated in the source. However, the source does not explicitly mention the 'Infrastructure Lead' role, so that specific title cannot be verified from this text. The core facts (person, org, co-founder status, and founding year) are confirmed.

NoteThe source is Anthropic's company/values page and does not contain personnel roster information or individual employee details. While it confirms Ben Mann works at Anthropic (if he is indeed a co-founder or employee), the specific claims about his role as 'Co-founder, Infrastructure Lead' and start date of '2021-01' cannot be verified or contradicted by this source. The source simply does not address these specific data points.
